Well, even if you replaced your rear sight, as long as it is centered you should be within an inch or two of the center at 10 yards. I would say adjust it to hit center at 10-15 yards. I find that a good distance since sometimes it is too hard to see a small bullseye at 25 yards. I shoot mostly 5-15 yards when I practice.

Oh yeah... I know exactly what you are talking about... everytime I switch out my sights my next range trip is with my sight slider to fine tune it... I like to hit dead on... you would be surprised how a few thousandths will move that bullet...

I wil take your advice. The sights were visually put on by a dealer. I have laser, in the barrel, sighted them in, at 25yds, but have yet to get to the range. As I said I did not want to waste a lot of time so using a good distance will help.
